Ai3 Alt Text — TYPO3 Extension

Ai3 Alttext (ai3_alttext) is the image alternative-text capability of the Ai3 Suite. It adds a backend module and a FormEngine field control to TYPO3 that generate accessible alt texts for images in the file storage using the ZAK-AI REST API.

Requirements

Dependency	Version
TYPO3 CMS	^13.4.0 | ^14.0
wegewerk/ai3_core	@dev

Installation

composer require wegewerk/ai3_alttext

wegewerk/ai3_core is pulled in automatically as a Composer dependency.

Quick start

1. Set the ZAK-AI credentials as environment variables:

   export ZAKAI_API_KEY=<your-api-key>
   export ZAKAI_SECRET=<your-secret>

2. Open File > AI3 metadata in the TYPO3 backend.

3. Select a folder, choose the images to process, and click Generate Alt-Texts with AI.

4. Review the AI suggestions and click approve (or approve all) to write them to the file metadata records.

Features

• Backend module under File > AI3 metadata for browsing folders and files in the TYPO3 file storage
• Batch generation - select multiple images and generate alt texts in one operation
• Review & approve workflow - AI suggestions are stored separately and must be approved before they are written to file metadata
• FormEngine field control - the extension adds a button to the file metadata edit form which queues a singe alt-text generation
• Recursive folder actions — accept all AI suggestions across an entire folder tree in one click

Configuration

This Extension does not provide any configuration settings. Configure the ZAK-AI credentials via environment variables. See ai3_core
